Let the starting point be the origin (0,0).
Let east be positive x, west negative x.
Let north be positive y, south negative y.

Starting at (0,0)
120km south: (0,0)+(0,-120)=(0,-120)
150 km east:(0,-120)+(150,0)=(150,-120)
200 km north: (150,-120)+(0,200)=(150,80)
The aircraft's currently 150 east and 80 miles north of the starting point.
